11 Claims.

This invention relates to a knock-down display device.

Merely by way of illustration, the same is shown as a display similar toand for the same purpose as the display device illustrated and describedin the patent to Nathan Joseph Leigh, No. 2,064,434, dated December 15,1936.

One chief object of this invention as distinguished from the patentdisclosure is to form such a display from a single blank.

Another and equivalent object of this invention is to form such adisplay from the stock, the amount of which is materially less in itsentirety than that required to produce the patent disclosure.

One chief feature of the invention consists in the formation of adisplay device of this general character from an integral blank so thatthe parts which form the display device to be set up for displaypurposes, may be so positioned that certain relationships are obtainedtherebetween and are retained therein without the use of adhesive or anyother connection other than that incorporated in the blank.

Another chief feature of the invention is to provide a lock orconnection between the paper board parts which is relatively simple andpositive in character.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims:

In the drawings, Fig. 1 is a plan view of the blank from which theintegral display device is formed.

Fig. 2 is a front view thereof in display position.

Fig. 3 is a top plan view of the same.

Fig. 4 is a rear view of the lower locking device embodying one featureof the invention.

Fig. 5 is a plan view similar to Fig. 1 and of a modified form of theintegral form of the invention.

Fig. 6 is a top plan view similar to Fig. 3 and of the form of theinvention shown in Fig. 5.

Fig. is a rear view similar to Fig. 4 and of the form of the inventionshown in Fig. 5.

In Figs. 1 to 4 of the drawings, there are illustrated two areas I andII which are integral with each other and are connected together by ahinge joint I2, since the areas are integral this joint permits twoareas or portions to be positioned angularly of each other to representtwo adjacent side walls of a tubular container for an article ofmerchandise. Extending oppositely from each of the areas, opposite thehinge connection therebetween, are the portions I3 and.

I 4 hingedly connected respectively by the score or crease lines I andI6 to the areas I0 and II, respectively. Portion I3 is suitably relievedas at I! and Ila and portion I4 is suitably relieved 5 as at I8 and I8a.although such relief need not be provided.

Such relievement in effect, therefore, provides two strip extensions I9on the portion I3 and strip extensions 20 on the portion l4. One of 10these strip extensions is provided with a socket or slot arrangement andthe opposite one is provided with a tongue arrangement. Herein each ofthe strips I9 includes an elongated slit 2I parallel to the hinge lineI5. Extending angularly from each end thereof is a slit 22 and the slits22 extend oppositely from each other and toward the hinge connection.

On the free end of the strap is a tongue portion 23 connected to portion20 by the re- 20 duced neck 24. The width of the neck portion 24 issubstantially the same as the length of the slit 2|. The depth of theneck portion is slightly greater than the thickness of the boardmaterial which preferably is of card board, suitably litho- 25 graphed,printed or the like. The greatest width of the spear-like tongue isslightly less than the greatest distance between the two angular slits22. The two complementary parts are associated together as shown clearlyin the upper middle portion of Fig. 3 and the central portion of Fig. 4.

Extending upwardly from each of the areas l0 and II are the extensions25 and 26, respectively, and these are connected thereto by the hinge orscore line connections 2'! and 28, respectively, which permit theinfolding of these extensions into the central angle formed by the twowall portions I0 and II when the latter are arranged in angular relationand are retained therein by the association of the extensions l9 and 20in locking relation.

It will be noted that the two extensions 25 and 26 are separated by aslit or slot arrangement 29- see Fig. l. The upper portion of the blank30 may have any suitable outline but preferably represents an article ofmerchandise or at least the upper portion thereof that would normally becontained within a tubular container, the representation of the twofront walls of which are provided by the portions I0 and I I. The lowerportion of this upper portion 30 is laterally enlarged as at 3| and 32.Portion 32 is integral with portion 26 and is hingedly connected theretoas at 33. Portion 3| is separate from portion 25 as shown, thisseparation slit being indicated by numeral 34 in Fig. 1. Since the upperportion 30 is connected to the lower portion of the device through theextension 26, the cooperative locking connection is effected through theextension 25.

The extension includes a slit 35 that extends from its free end 36toward the hinge or foldable connection 21, thereby providing an area 31which may or may not have a scored connection38 with the extension 25 asshown. To facilitate assembly or set up of the blank, this scoreconnection is provided. It is not, however, essential, unless the boardfrom which the material is made is not sufiiciently flexible.

The several portions of the blank areset up as follows: The two portions25 and 26- are folded rearwardly and downwardly so as to lie behind theportions I0 and II. Then the upper portion is folded upwardly about thehinge connection 33 so that the major area of the portion 30 is exposedabove the two portions I0 and II. Then the two portions I0 and I I- aremoved into angular relation. In this movement the portion 31 is elevatedslightly with respect to the remainder of the extension 25 and as theparts I0 and II assume an angular relation, the tongue 3| passes intothe slot until the edge 30a.'of the upper portion engages the edge ofthe portion 31 at the slit or slot portion 35. Such movement causes theupper portion 30 toassume a position so that it is substantially arcuatein cross section. In turn each of the tongues 23 is passed into thecomplementary slit portions 2 I22. The device then is in assembledrelation, self-sustaining and represents by the exposed portions. I0 andI I two adjacent walls of a tubular container and by the upper portion30 a front portion of a representation of a tubular article normallycontained within such a container.

When in this relationship, the portions I3-I4, the tongue and slitconnecting extensions I9-20, the intermediate portion or extensions25-26 and the lateral extending portions 3 I32 are all concealed withinthe central angle formed by the two Wall representing portions I0 and II.

Portion may be included, whenever desired, as an integral part ofportion 30 and be printed as an arrow extended across portion 30,pointing to advertising matter printed upon portions I0 and II.

In Figs. 5 to 7 of the drawings, there is illustrated .a modified formof the invention. In said figures, numerals of the one hundred seriessimilar to the primary series employed with reference to Figs. 1 to 4,inclusive, are herein employed to designate like, similar or equivalentparts.

This form of the inventiondiifers in three'main respects. In the firstinstance, the side'portions I13 and I I4 are not of relieved form suchas shown in Fig. l. The side portion I I4 includes the locking tongues I23 connected thereto by the neckv portions I24 of substantially thesamegeneral character as described with reference torthe neck portions24, shown in Fig. 1, as compared with the width or distance between theends'of the slits 22 in said figure. Herein in Fig. 5 the oppositelydirected slit portions I22are also directed toward score portion H5 butinclude arcuate extensions I26 instead of being individualized withrespect to each other are herein shown integral and are provided with ahinge connection I29. The latter, however, instead of being a continuousextension of the hinge connection H2, is, although in alignment,separated therefrom by the trian-' gular notch I290. which is positionedat the intersection of the hinge connections I28I2'| and I29(proiected)-H2.

The third departure in this form of the invention is as follows: Theportion I3 projecting from the side edge I30a is of hook formation. Theportion I25, instead of being formed as portion 25 is formed, see Fig.1, in the present instance includes a D-shaped slit I35 defining atongue portion I31, the outline of the latter being completed, ifdesired, by the scoring I38.

The setting up of this form of display device is similar to thatpreviously described with reference to the form of the invention shownin Figs. 1 to 4, inclusive. It is, however, not identical theretobecause of the difference in the construction of the interlock betweenthe hook portion I3I- and the portion I 25. Furthermore, there is aslight difference by reason of the fact that portions I25 and I26 areintegral with each other and not divided as shown, with reference toparts 25xand 26, separated by the slot 29-see Fig. l.

The portions I30, 25 and I26 are turned downwardly and rearwardly withreference to portions I I0 and I I I, thenportion I30 is turned upwardlyon the hinge. portion I33. The hingedly connected portions H0 and IIIand I25 and. I26 are thenturned from the fiat relation upon the scoreconnections I I2 and I29, then the two portions H4 and H3 are turnedinwardly so as to lie in substantially the same plane and when thuspositioned, the tongues are lockingly associated with the cooperatingslits to retain the device in substantially triangular relation. Also,the hook member I3I-is then associated with the D-shaped slot or slitI35 so that the opposite side I30riv of the extension I30 is locked tothe portion I25. This form of the invention while it utilizes a littlemore stock by reason of the omission of the cutouts I'I, Ila, I8 andI8ashown in Fig. 1-does have the advantage that there is additionalinherent strength at the connection between the portion I30 and the twocontainer wall forming portions H0 and III, by reason of the fact thatportions I25 and I26 are integral with eachother and hook member I3I islocked to portion I25 and theopposite, lateralextension I 32 on theportion I30 is integral with the portion I26.

Note in each instance, the slot orslit 34 and I34 completely separatesthe portion 30 and I30, respectively, from the portions 25 and I25 andare partially separated from the portions 26 and I26, respectively, saidslots terminating at 34a and I34a, respectively.
